Wow... I should of listen to you 10 months ago... After getting no useful help from iZotope support I finally, out of frustration, installed iLok...  All the O9 Advanced components now load swiftly, 2-3 seconds 😁. So, thanks @earhears for the tip! iLok installs Apples "Bonjour Service",  I guess it's used for iLok license management, but since I'm 100% computer authorized I stopped the service which, fortunately, had no negative effects.  So why iLok fixed the load times is a still mystery.
